Astronaut Spies Fiery River from the International Space Station

Astronaut Jack Fisher, part of Expedition 51/52 aboard the International Space Station, snapped this fantastic image from orbit on August 6, 2017. You can follow Fischer on Twitter @Astro2fish to see more of his photos from space.

A big thanks went out to @DaveAtCOGS and @CaliaDomenico for identifying the rivers. Running along the border of Zambia, Botswana and Zimbabwe in Africa, the Cuando and Zambesi Rivers (from left to right) glow with a fiery intensity.

Fischer, a flight engineer aboard the space station for the next few months, will be completing a planned 300 experiments "ranging from plant growth to bone growth," according to a NASA interview.

With all the scheduled activities, extravehicular activities, experiments and more, Fischer predicts his biggest challenge in space will be using the toilet.
